Abstract

Polyurethane concentrates for making medical exchangers for flat membranes or hollow fibres are obtained from polyurethane generating compositions comprising at least one polyisocyanate, preferably non-aromatic, monomer or prepolymer; at least one polyol monomer or prepolymer; and at least 2 wt.%, in relation to total weight of polyols, at least one dialkylsulphoxide compound. Also claimed is method for reducing cytotoxicity of medical articles made from polyurethane.
